B21B1/00 - CPC Classification

Classification description:

Metal-rolling methods or mills for making semi-finished products of solid or profiled cross-section ; Sequence of operations in milling trains; Layout of rolling-mill plant, e.g. grouping of stands; Succession of passes or of sectional pass alternations

Sub-classes:

B21B1/02 » for rolling heavy work, e.g. ingots, slabs, billets, in which the cross-sectional form is unimportant 29
B21B1/08 » for rolling {structural sections, i.e.} work of special cross-section, e.g. angle steel 35
B21B1/16 » for rolling {wire rods, bars, merchant bars, rounds} wire or material of like small cross-section 90
B21B1/22 » for rolling {plates, strips,} bands or sheets of indefinite length 311
B21B1/38 » for rolling sheets of limited length, e.g. folded sheets, superimposed sheets, {pack rolling} 86
B21B1/40 » for rolling foils which present special problems, e.g. because of thinness 60
B21B1/42 » for step-by-step or planetary rolling 9
B21B1/46 » for rolling metal immediately subsequent to continuous casting 79
